TO ALL WHOM IT MAY CONCERN:

Be it known that I, PETER BARRY, of Newark, in the county of Essex, in the State of New Jersey, have invented a new and useful Improvement in Blind-Wiring Machines; and I hereby `declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to-make and use the same, reference being had to the accompanying drawing, ,forming part of this specific-ation, in which drawing- Figure 1 is a front elevation of a machine that contains my improvement. v

Figure 2 isa rear elevation. l

Figure 3 is a detail of the feeding mouth of the machine, showing the spring, the cut-off, and the plunger.

Figure 4 is a plan view.' I

This invention relates to machines for wiring slats, stiles, and other parts of blinds or other articles, and it embraces a cut-off, which prevents more than one staple being placed beneath the .plunger at the same time, and

other novel features which are hereinafter described. y

The letter A designates a vertical frame, which carries the main operative parts of the machine. Said frame in its lower position rests upon a bed-plate, A2, from which rises a vertical slottedguide, V, to which the frame A is secured by means of a clamping-screw, X, one or more of which may be used for this purpose. The frame is kept straight with respect to the guide by means also of projections W W, which enter the slot of the guide and cause the frame to remain in the same vertical plane,'when placed in higher or lower positions on the guide, to suit work of different thicknesses. The bed-plate A2 rests on a table, A1, near whose front edge is placed a spring, Q, that presses the work or stu1 to be wired against the front edge of said bed-plate, whose fro'nt part i-s made adjustable in the direction of the spring by means of a tongue and slot, as indicatedat bon said bed-plate in iig. 4. The letter O designates a stile or blind-rod, and P is a notched feeding rack or bar, whose rear end is made with a shoulder, as shown in tig. 4, which abuts against the rear end of the blindrod and carries it along beneath the plunger, the blind-rod or other article which is 'to beA wired being next the bed-plate A2, and the spring Q being allowed to bear against the notched bar,'to crowd the latter against the rod. The necessary forward step by step movement of the feeding-bar and blind-rod is effected by means of a pawl, I, which reciprocates in a horizonital slot in the frame A. Behind the lower rear corner of said slot is an adjustable shoe, M, secured to the face of the frame by a sct-screw, for the purpose of regulating the feed by throwing up the pawl I, and, holding it up and above the notched bar, so as to prevent-its engagement' therewith during the earlier part of the forward movement of the pawl. The object of this arrangement is to effect the movement of the blind-rod at each reeiprocation of the pawl for only .the distance the lstaples are required to bc apart from each other, and by lifting the pawl and holding it up until it comes near to the proper notch, the movement of the notched bar is regulated without limiting or altering the extent ofthe reciprocation ofthe pawl itself. The pawl L is moved by means of a bent lever, S, pivotcd at t to the back of the frame, through the agency of a head or block which slides in the slot N, to opposite sides of which head or block the pawl and the level' are connected, the connection of the said lever being by means of a pin which works in a slet in -the lever, as shown in fig. 2. The upper end of the bent lever S is connected to the hand-lever E, which in this example is made the means of operating the mechanism by means of a pin which extends from the slide c going through lever S, and working in a slot in said hand-lever. The said hand-lever is pivoted to the frame at the point Z. The slide e moves between vertical guides formed in the frame A, and its lower end is arrested by a stop, U, which projects from the solid part of the frame, so as to limit its downward movement. The letter D designates the plunger which drives the wires or staples. It is attached to the slide c by means of. a head or blockwhich projects from the slide and works in a vertical slot, K,'made in the frame. The plunger D is directly above a feeding mouth for feeding the wires or staples, which mouth is formed by the front of the frame in combination with4 the lat-eral blocks C C and the rigid guide strip B, which latter is fastened to thefaces of the blocks C C by means ofv ears J J that project laterally from the foot of the strip' and receive screws which fasten them to thel blocks. Additional means may-also be employed t0 secure the strip to the machine and keep it in an unyielding condition. The upper edge of the strip inclines towards frame A, and its lower end is curved to allow the wires or staples, which in practice are placed'astraddlc of the strip, as shown in the drawing, to slide easily olf the strip and enter the mouth or space formed below the plunger as above stated. The size of amm 2 said mouth or space is arranged to suit the size of the wires or staples used in the operation, and in the said mouth 4I place an clue-tio plate, R, which is in this example secured to the frame in such a way that its lower part springs across the lower part of the feed-mouth and arrests the wire or staple in its descent after leaving the guide strip. The staples :ire strung upon the edge of the guide strip andallowed to descend 'by gravity towards the feed-mouth, being arrested near the end of' the guide strip by a cut-oli', I",` consisting of a lever of curved shape, whose upper end is slot-ted to receive pins G G, which go through the slot into the frame, and serve to guide the movements of the cut-oil'. The lower end of' the cnt-oil is so bent as to come before the plunger D, going between guides c e, which guide it so that it operates with accuracy in conjunction with tbc guide strip B, the bottom of the said cut-ot being bifureated, so as to t on the upper edge of the said strip and enable it to interpose between the lowermost staple and those above it, so as to arrest the latter and allow only the former to leave the strip and descend into the feeduionth. 'Ibe movements of the cut-oil are accomplished by means of the reciprocations of the slide c through the horizontal lever H, which is pivotcd to the frame nt a point, I, near to said cut-oil` lever, and connected both to the said slide c and Vto the cut-off F by pins going through slots in the ends of said level II. The movements of the plunger D and cut-OWF are so timed that the cut-oil` is up when the plunger is down, thereby allowing one of the staples to slide on the guide strip downwards against the face of the plunger while the latter is descending towards the stile or rod O. At the next movement of the hand-lever E the plunger is lifted, and while it is ascending the cut-oildescends and cuts oil' the said staple from those above it, and allows it alone 'to slide off the guide strip into the feed-mouth. The distance to which the staple deseendsis determined by the position of the elastic or spring-plate R, the distance beingr great enough to bring the back of the staple fully below the bottom of the plunger, so that the latter can come squarely upon it in order to drive it into the stile or rod O beneath, the spring-plate being pressed out ofthe way to allow the staple and plunger to descend beside it. At each elevation of the plunger the fceding-bar or rack P and the stile or rod O are moved along the proper distance to receive a Fresh staple.

What I claim as new, and desire to secureby Letters Patent, is-

1. The independent cut-oil" F, arranged to opelate upon the staples by coming between them from above7 substantially as described.

2. I also claim the independent cut-oil` in combination with thc guides c c, which guide its free end to the guide strip E, substantially as shown. Y

i 3. I also claim the combination of the elbow-lever S, the slot N, the pawl L, and the adjusting-shoe M,

substantially as shown.

4.-. I also claimA in combination the feeding-pawl L, the adjusting-shoe M, and thc feeding-imi' or ruck l), substantially as shown.

5. I also claim the application of a spring-plate, It, to the fecding-n1outh or space below the plunger, when arranged and combined with a rigid or unyiclding guide strip B, substantially asset forth.
